VOLUME - this is the drive sent to the first 2 gain stages. In addition, this is a Push/Pull knob: "In" is the standard BOLD (ROCK) tone path ..... pull the knob out for the SMOOTH (JAZZ) path.

MASTER - this is the overall output volume. This controls the level going to the amplifier or to the input of the Cab Simulation circuitry .... when using the Cab Simulator, it is advised to keep the master below 12:00 to minimize possible overloading of the input.

BASS - MID - TREBLE - the EQ follows a topology similar to blackface amplifiers with tweaks influenced by the original series of amplifiers by Alexander Dumble. Very interactive!

OD GAIN - this controls the level of the signal being introduced into an additional 2 gain stages. This control also fills in as a power switch - turn the control fully anti-clockwise and the power is disconnected from the circuit.

OD LEVEL - think of this as a master volume for the OD stage .... overall output is still governed by the MASTER VOLUME control.

CAB SIM GAIN - controls the gain/input level into the Cab Simulator circuit. This is very sensitive filtering circuitry, so I have also implemented a trimmer on the board to control the input gain to minimize clipping.

BRIT / CALI SWITCH - Choose the voicing of the output! Use your ears to find the one you like.
